Description

Technical Field

[0001] The present invention relates to the technical field of high-speed water entry experiments of vehicles, and particularly to a snorkeling underwater interception and protection system for a high-speed water entry vehicle. Background Art

[0002] Nowadays, the competition among countries for marine equipment is becoming increasingly fierce, and a large number of experimental studies have been carried out on various marine equipment. As one of the major marine equipment, the high-speed water entry vehicle has high economic costs for prototype tests, a long test cycle span, and inconvenient coordination of test equipment and sites. Therefore, it is very necessary to carry out model tests with relatively low costs and relatively small requirements for equipment and site scales. However, in the cross-medium high-speed water entry test, the model is heavy, the water entry speed is high, and the underwater ballistic range is large. After the vehicle enters the water, it will cause a large impact on the pool wall, which will not only damage the pool wall and affect the surrounding equipment, but also cause damage to the vehicle itself and the internal test equipment. At the same time, after the water entry test is completed, due to insufficient light in the test field and at the bottom of the pool, it is extremely difficult to find and salvage the vehicle in the pool. These pose strict requirements for the protection of the pool structure and existing equipment, as well as the interception and salvage of the model.

[0003] In order to carry out the experimental research on high-speed water entry vehicles safely and efficiently, there is an urgent need to establish an underwater interception and protection system that can resist the impact of high-speed water entry vehicles, adjust the water depth position at any time, intercept and protect from multiple angles, and facilitate the recovery operation of the vehicle. The patent with publication number CN114112294A discloses an interception and recovery device for high-speed water entry model navigation tests. This patent can be used for the interception and recovery operation of high-speed water entry vehicle tests. However, the water depth position of this patent cannot be freely adjusted. Moreover, this patent uses multiple layers of steel plates for deceleration interception, and there is a hard contact between the test model and the interception plate, which may damage the model. And when the vehicle enters the water at a small angle, the hard contact may cause the impact rebound of the model, that is, there may be rebound damage to the model during interception, and it cannot provide all-round protection. In addition, it is relatively difficult to salvage and recover the vehicle; the patent with publication number CN217754029U discloses a protection and interception device for high-speed surface ships. This patent can be used for the protection and interception operations of high-speed surface ships or vehicles, but this patent cannot be applied to the protection, interception, and recovery operations of underwater vehicles. Therefore, in order to meet the actual needs of the development of marine equipment and promote the development of high-speed water entry vehicle test technology in the laboratory, it is necessary to develop a snorkeling underwater interception and protection system for high-speed water entry vehicles with adjustable water depth position, convenient recovery operation, and applicable to underwater multi-angle all-round interception and protection. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the existing water surface high-speed ship protection and interception device cannot be applied to the protection, interception and recovery operations of underwater vehicles, so as to provide a snorkeling underwater interception and protection system for high-speed water-entry vehicles.

[0005] To solve the above technical problem, the present invention provides a snorkeling underwater interception and protection system for high-speed water-entry vehicles, including: a main body, the main body is a frame structure with one end open, and wire meshes are provided on both side walls of the main body; a protection layer structure provided on the main body; a first inflation structure and a second inflation structure, the first inflation structure is provided on the side wall of the main body, and the second inflation structure is provided on the bottom of the main body, and both the first inflation structure and the second inflation structure are used to adjust the water depth position of the main body; a baffle provided at one end of the main body and located below the opening.

[0006] Further, the main body includes a surrounding frame, a top frame, a middle layer frame, and a bottom frame, the top frame is provided on the top of the surrounding frame, the middle layer frame is located in the middle of the surrounding frame, and the bottom frame is located at the bottom of the surrounding frame.

[0007] Further, a plurality of columns are provided between the middle layer frame and the bottom frame.

[0008] Further, the protection layer structure includes a first protection layer, a second protection layer, and a third protection layer, the first protection layer is provided on the surrounding frame and the middle layer frame, the second protection layer is provided on the top frame, and the third protection layer is provided on the bottom frame.

[0009] Further, the first protection layer includes a blocking cloth, a wooden board, and an aluminum plate arranged in sequence from top to bottom.

[0010] Further, the second protection layer is a blocking cloth.

[0011] Further, the third protection layer includes a blocking cloth and an aluminum plate arranged in sequence from top to bottom.

[0012] Further, both the first inflation structure and the second inflation structure are air bags.

[0013] Further, the middle part of the air bag is cylindrical, and both ends are conical.

[0014] Further, the main body is made of channel steel.

[0015] The technical solution of the present invention has the following advantages:

[0016] 1. The snorkeling underwater interception and protection system for a high-speed water-entry vehicle provided by the present invention includes: a main body, which is a frame structure with an open end, and wire meshes are provided on both side walls of the main body; a protection layer structure provided on the main body; a first inflation structure and a second inflation structure, the first inflation structure is provided on the side wall of the main body, and the second inflation structure is provided at the bottom of the main body, and both the first inflation structure and the second inflation structure are used to adjust the water depth position of the main body; a baffle plate provided at one end of the main body and located below the opening.

[0017] By providing an open end on the main body, it is convenient for the vehicle to enter the main body through this opening, so as to realize underwater interception of high-speed water-entry vehicles under various working conditions; by providing wire meshes on the main body, it can reduce resistance, play a protective role and facilitate drainage; by providing a protection layer structure on the main body, multi-angle and all-round protection can be realized; at the same time, through the setting of the first inflation structure and the second inflation structure, the water depth position of the main body can be adjusted, and then by using the baffle plate provided at one end of the main body, the second inflation structure can be protected to avoid damage to the second inflation structure.

[0018] The snorkeling underwater interception and protection system for a high-speed water-entry vehicle, through the design of a multi-layer protection structure, intercepts the model at a specified position, and can protect the pool wall and the platform without generating a rigid connection relationship with the pool wall and the platform; it can realize underwater interception of high-speed water-entry vehicles under various working conditions in indoor pool experimental conditions, protect the pool wall, peripheral equipment and the vehicle itself, solves the problem that traditional large-scale high-speed water-entry experiments can only be carried out in the field, greatly reduces the experimental cost, and removes the experimental site limitation.

[0019] The snorkeling underwater interception and protection system for a high-speed water-entry vehicle can reduce the difficulty of salvaging the high-speed water-entry model. In traditional water-entry experiments, in order to facilitate salvaging, a positive buoyancy model is often used, that is, the buoyancy of the model is greater than the gravity after it enters the water, so the model can automatically float on the water surface. However, from the perspective of the experimental mechanism, this design is not conducive to the development of the experiment. The snorkeling underwater interception and protection system for a high-speed water-entry vehicle can effectively block and salvage the model, so the mass of the model is no longer limited, and there is a great improvement from both the experimental principle and the perspective of salvage and recovery.

[0020] The snorkeling underwater interception and protection system for a high-speed water-entry vehicle uses multiple combined methods to block, prevent damage to the model after it impacts the blocking device, and can effectively protect the model. At the same time, multiple blockings can effectively realize blocking and recovery.

[0021] The snorkeling underwater interception and protection system of the high-speed water-entry vehicle adopts a "net bag type" interception method, that is, the setting of the wire mesh can achieve multi-angle and all-round protection. Even if the model bounces after hitting the buffer plate, it can still be intercepted by the wire mesh, ensuring that the model falls inside the snorkeling underwater interception and protection system of the high-speed water-entry vehicle, realizing effective protection of the pool structure and effectively ensuring the effective recovery of the model.

[0022] The snorkeling underwater interception and protection system of the high-speed water-entry vehicle has a flexible adjustable position. For different water-entry points of the model, the interception and protection system can be placed at a fixed point to ensure that the model can fall into the interception and protection system. Compared with the full-pool protection, this interception and protection system effectively improves the protection and interception efficiency and has a lower cost.

[0023] The snorkeling underwater interception and protection system of the high-speed water-entry vehicle has a wide range of application scenarios. It can be applied to the interception and protection, salvage and recovery and other experimental studies involved in related water conservancy and ocean engineering such as the high-speed water entry of vehicles, submarines and ocean robots, and has high practical engineering significance.

[0024] The snorkeling underwater interception and protection system of the high-speed water-entry vehicle has simple and easily available components, which can effectively reduce the cost of the whole set of devices. If a certain part is damaged, it can be quickly replaced. It adopts a semi-open structure, that is, a slipper style, which can intercept and protect the model with a small water-entry angle in the high-speed water-entry test.

[0025] 2. In the snorkeling underwater interception and protection system of the high-speed water-entry vehicle provided by the present invention, both the first inflatable structure and the second inflatable structure are air bags. The whole interception and protection system provides buoyancy through the air bags, and realizes the depth adjustment of the main body by inflating and exhausting the air bags, adjusting different interception positions. It can realize the functions of adjusting the position and depth of the protection system, and solve the problems of large landing point range and wide angle of the model in the high-speed water-entry test.

[0040] The preferred embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.

[0041] Please refer to Figures 1 to 5 As shown, the present invention provides a snorkeling underwater interception and protection system for a high-speed water-entry vehicle, including: a main body 1, the main body 1 is a frame structure with an opening 2 at one end, and wire meshes 3 are provided on both side walls of the main body 1; a protective layer structure 4, which is arranged on the main body 1; a first inflation structure 5 and a second inflation structure 6, the first inflation structure 5 is arranged on the side wall of the main body 1, and the second inflation structure 6 is arranged at the bottom of the main body 1. Both the first inflation structure 5 and the second inflation structure 6 are used to adjust the water depth position of the main body 1; a baffle 7 is arranged at one end of the main body 1 and is located below the opening 2.

[0042] By providing an opening 2 at one end of the main body 1, it is convenient for the vehicle to enter the main body 1 through the opening 2, so as to realize the underwater interception of high-speed water-entry vehicles under various working conditions; by arranging wire meshes 3 on the main body 1, it is beneficial to reduce resistance, play a protective role and facilitate drainage; by arranging a protective layer structure 4 on the main body 1, multi-angle and all-round protection can be realized; at the same time, through the arrangement of the first inflation structure 5 and the second inflation structure 6, the water depth position of the main body 1 can be adjusted, and then by using the baffle 7 arranged at one end of the main body 1, the second inflation structure 6 can be protected to avoid damage to the second inflation structure 6.

[0043] The snorkeling underwater interception and protection system for the high-speed water-entry vehicle, through the design of a multi-layer protection structure, intercepts the model at a specified position, and can protect the pool wall and the platform without generating a rigid connection relationship with the pool wall and the platform; it can realize the underwater interception of high-speed water-entry vehicles under various working conditions under the experimental conditions of an indoor pool, protect the pool wall, peripheral equipment and the vehicle itself, solves the problem that traditional large-scale high-speed water-entry experiments can only be carried out in the field, greatly reduces the experimental cost, and removes the experimental site limitation.

[0044] The snorkeling underwater interception and protection system for the high-speed underwater vehicle can reduce the difficulty of salvaging the high-speed underwater model. In traditional underwater experiments, in order to facilitate salvaging, a positive buoyancy model is often used, that is, the buoyancy of the model is greater than the gravity after it enters the water, so the model can automatically float on the water surface. However, from the perspective of the experimental mechanism, this design is not conducive to the development of the experiment. The snorkeling underwater interception and protection system for the high-speed underwater vehicle can effectively intercept and salvage the model, so the mass of the model is no longer limited, and there is a great improvement both in terms of the experimental principle and salvage and recovery.

[0045] The snorkeling underwater interception and protection system for the high-speed underwater vehicle uses a combination of multiple methods to intercept, preventing damage to the model after it impacts the interception device, and can effectively protect the model. At the same time, multiple interceptions can effectively achieve interception and recovery.

[0046] The snorkeling underwater interception and protection system for the high-speed underwater vehicle uses a "net bag type" interception, that is, the setting of the wire mesh 3 can achieve multi-angle and all-round protection. Even if the model bounces after hitting the buffer plate, it can still be intercepted by the wire mesh 3, ensuring that the model falls inside the snorkeling underwater interception and protection system of the high-speed underwater vehicle, achieving effective protection of the pool structure, and at the same time effectively ensuring the effective recovery of the model.

[0047] The snorkeling underwater interception and protection system for the high-speed underwater vehicle has a flexible adjustable position. For different underwater entry points of the model, the interception and protection system can be placed at a fixed point to ensure that the model can fall into the interception and protection system. Compared with the full-pool protection, this interception and protection system effectively improves the protection and interception efficiency and has a lower cost.

[0048] The snorkeling underwater interception and protection system for the high-speed underwater vehicle has a wide range of application scenarios. It can be applied to the interception, protection, salvage and recovery and other experimental studies involved in the high-speed underwater entry of underwater vehicles, submarines, and ocean robots and other related water conservancy and ocean engineering, and has high practical engineering significance.

[0049] The snorkeling underwater interception and protection system for the high-speed underwater vehicle has simple and easily available component structures, which can effectively reduce the cost of the whole set of devices. If a certain part is damaged, it can be quickly replaced.

[0050] Adopting a semi-open structure form, that is, a slipper style, it can intercept and protect the model with a small angle of underwater entry in high-speed underwater experiments.

[0051] In some alternative embodiments, the main body 1 includes a surrounding frame 8, a top frame 9, a middle frame 10, and a bottom frame 11. The top frame 9 is provided at the top of the surrounding frame 8, the middle frame 10 is located in the middle of the surrounding frame 8, and the bottom frame 11 is located at the bottom of the surrounding frame 8.

[0052] The main body 1 is a cuboid frame, and the main body 1 is made of channel steel. The cuboid frame is jointly composed of the surrounding frame 8, the top frame 9, the middle layer frame 10, and the bottom frame 11.

[0053] Considering the actual situation of hoisting and transportation at the test site, the bottom frame 11 is made into two segments, and the two segments are fixedly connected. Specifically, the middle layer frame 10 and the bottom frame 11 are arranged in the same way, and a plurality of struts 12 are provided between the middle layer frame 10 and the bottom frame 11. The setting of the struts 12 can effectively support the middle layer frame 10 and the bottom frame 11, and effectively ensure the connection stability between the middle layer frame 10 and the bottom frame 11. The two layers are supported by the struts 12, and the struts 12 are arranged at the positions where the transverse and longitudinal members intersect. The baffle 7 is arranged on the bottom frame 11, and the steel plate is fixedly connected to the bottom frame 11.

[0054] Moreover, a lifting hook 19 is provided on the main body 1, and is connected to the lifting hook 19 by a steel wire rope, which is convenient for the hoisting and transportation of the interception and protection system.

[0055] Specifically, the protective layer structure 4 includes a first protective layer 13, a second protective layer 14, and a third protective layer 15. The first protective layer 13 is provided on the surrounding frame 8 and the middle layer frame 10, the second protective layer 14 is provided on the top frame 9, and the third protective layer 15 is provided on the bottom frame 11.

[0056] Among them, the first protective layer 13 includes a blocking cloth 16, a wooden board 17, and an aluminum plate 18 arranged in sequence from top to bottom. The combination of the wire mesh 3, the blocking cloth 16, the aluminum plate 18, and the wooden board 17 can effectively achieve the soft recovery of the high-speed water-entry model, prevent self-damage of the model due to insufficient buffering after hitting the blocking device, provide a speed reduction and energy consumption space, and facilitate the recovery of the model. At the same time, the wire mesh 3, the blocking cloth 16, the aluminum plate 18, and the wooden board 17 are all replaceable materials, and can be disassembled and replaced in time if damaged.

[0057] Specifically, the second protective layer 14 is a blocking cloth 16, and the blocking cloth 16 is laid above the main body 1 for protection to prevent the model from jumping out of the range of the protective frame, and is installed inside the main body 1. The net bag type interception method adopted by the main body 1 can effectively achieve the comprehensive interception of the model and prevent the model from rushing out of the interception range due to movements such as slipping and ricocheting.

[0058] The third protective layer 15 includes a blocking cloth 16 and an aluminum plate 18 arranged in sequence from top to bottom. The setting of the third protective layer 15 can effectively achieve the soft recovery of the high-speed water-entry model, prevent self-damage of the model due to insufficient buffering after hitting the blocking device.

[0059] A barrier net is added around the main body 1 to increase the protection area and prevent problems such as the randomness of the trajectory of the high-speed water-entry model and the damage of the test model and the main body 1 caused by the possible bouncing during the blocking process, which is difficult to completely intercept.

[0060] In some alternative embodiments, both the first inflatable structure 5 and the second inflatable structure 6 are airbags. The middle part of the airbag is cylindrical, and both ends are conical.

[0061] The entire interception and protection system provides buoyancy through the airbag, and adjusts the depth of the main body 1 by inflating and deflating the airbag to adjust different interception positions. It can realize the functions of adjusting the position and depth of the interception and protection system, and solve the problems of large landing range and wide angle of the model in the high-speed water-entry test.

[0062] At the same time, according to the relationship between the center of gravity and the center of buoyancy, a double-layer inflatable airbag is set to increase the center of buoyancy of the interception and protection system, which can improve the stability of the main body and prevent it from capsizing when receiving the impact of the model.

[0063] Among them, the first inflatable structure 5 has two airbags, which are respectively arranged on both sides of the main body 1; the second inflatable structure 6 has eight airbags, and the eight airbags are arranged at intervals on the bottom of the main body 1. Specifically, the number of airbags in the second inflatable structure 6 can be set according to the actual situation.

[0064] The snorkeling underwater interception and protection system for a high-speed water-entry vehicle provided by the present invention can intercept the vehicle in the high-speed water-entry test in a decompression environment in all directions on the premise of ensuring strength. By adjusting the inflation and deflation in the first inflatable structure 5 and the second inflatable structure 6, the water depth position of the interception and protection system is adjusted to cope with the problems of water entry at different angles and ballistic divergence, which can effectively protect the safety of the pool wall, surrounding instruments and the vehicle model itself, avoid serious damage caused by impact, and facilitate the recovery operation of the vehicle model in the case of insufficient light.

[0065] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
